i want to get 4 pro 60's for my new 211 to replace the stock deafcon III's. Do you think the pro 60's sound quality will be an upgrade?? I will be pushing it with my kicker sx900.4. i am looking at the pro 60's due to not hitting my head constantly, i think the pro 80's will hang lower. any opinions??

The 60s will be a great upgrade, but if you want a fuller deeper sound consider the Pro80s! I went with a pair of the Pro485s and they sound amazing behind boat. They are being powered by a Rockford Power 600w amp. Its down right funny at times how loud they are while behind the boat or in the water with the boat playing tunes. If you want to be more conservative with space and volume the 60s will be perfect.
